SPECIFICATION forming part of Letters Patent No. 494,392, dated March28, 1893. Application iiled March 30, 1892. Serial No. 427,022. (Nomodel.)

To all whom, it may concern.;

Beit known that I, GEORGE SPENCER, a citizen of the United States,residing at Old Mission, in the county of Kootenai and State of Idaho,have invented certain new and useful Improvements inAntit'riction-Bearings; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to ro which it appertains to make and use thesame.

My invention relates to improvements in bearings for rolling stock, suchas cars, dto., and it consists in a certain novel construction andcombination of parts, which will be fully described hereinafterandparticularlypointed out in the claim.

In the drawings: Figure l is a side View of the improved bearingdetached. Fig. 2 is a similar view showing a wheel and axle in opzoerative position. Fig. 3 is an edge view. Fig.

4 is a bottom plan View.

The bearing is preferably made in the form of an attachment which isapplicable to any ordinary vehicle, and it consists of a plate A 2 5provided with twin hangers B B, the lower ends of which are recessed toform half-bearings E E, bearing-plates G G secured to the lower ends ofthe hangers to complete the bearings E E, and antifriction rolls C Chaving 3o their spindles D D fitted in saidbearings. These rolls operateclose together and are adapted to bear upon the axle F, Fig. 2, by whichthe wheels G are connected.

The operation of the device will be readily understood. The lower endsof the hangers are inclined upward toward their inner ends or arearranged respectively perpendicular to lines which converge downward andmeet beneath the center of the axle F. The thrust upon the hangers is aresultant ot' two forces, 4o acting respectively, vertical andhorizontal, and the lower faces of the hangers are arrangedperpendicular to these resultantlinesot' thrust, so that the thrust actssquarely upon the half bearing therein. p

Having described my invention, I claim- An anti-friction bearing adaptedto be interposed between the body of a car and the axles thereof, andcomprising the horizontal plate provided at its ends with pairs of down-5o wardly and inwardlyinclined hangers, having their lower ends cut atan angle and provided with semi-cylindrical bearing recesses, the twoanti-friction rollers arranged between the hangers of each pair andprovided with trunnions extending from both faces of each roller andarranged in the bearing recesses, and the bearing plates retaining thetrunnions in the bearing recesses, substantially as described.

GEORGE SPENCER.
